In April last year, the Rana Plaza factory building in the Bangladeshi capital of Dhaka collapsed - leaving more than 1,100 dead and around 2,500 injured. In this documentary for the This World strand, some of the survivors reveal how they escaped, with many rescued by locals who risked their lives crawling into the rubble to save them. The film also investigates the incredible growth of the Bangladeshi garment industry as well as claims that greed and high-level corruption were partly responsible for the tragedy.
